Shrub rose plant named ‘Poultc011’

ABSTRACT

A new garden rose plant of the shrub class which has abundant, red flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical classification: Rosa hybrida.

Variety denomination: ‘Poultc011’.

SUMMARY OF THE CLAIMED PLANT

The present invention constitutes a new and distinct variety of garden rose plant which originated from a controlled crossing between the female seed parent plant, an unnamed seedling (non-patented), and the male pollen parent plant, an unnamed seedling (non-patented). The two parents were crossed during the summer of 1997, and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘Poultc011’.

The new variety may be distinguished from its female seed parent, by the following combination of characteristics:

-   -   1. ‘Poultc011 has of low growth height ranging from 40 to 60 cm.         The female parent plant is less compact, growing to 100 cm in         height.     -   2. ‘Poultc011’ exhibits flowers with a smaller diameter than         those of the unnamed female parent.     -   3. ‘Poultc011’ develops more flower buds than observed on the         seed parent.

The new variety may be distinguished from its pollen parent by the following combination of characteristics:

-   -   1. The claimed plant has slightly larger flowers than the pollen         parent.     -   2. ‘Poultc011’ bears flower buds in larger clusters than         observed on the pollen parent plant.

The objective of the hybridization of this rose variety was to create a new and distinct variety for garden use with unique qualities, such as:

-   -   1. Uniform and abundant red flowers;     -   2. Vigorous, but compact growth when propagated both as a budded         rose and on its own roots;     -   3. Exceptional disease resistance; and     -   4. Suitability for rose container culture.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poultc011’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter of 1997 and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘Poultc011’ was selected in the spring 1998 by the inventor as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poultc011’ by traditional budding and rooted cuttings was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in July, 1998. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poultc011’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poultc011’, as observed in its growth in a field nursery in Odense Denmark. Observed plants are 3 years of age, grown on Rosa multiflora understock. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety ‘Poulharmu’, a rose variety from the same inventor described and illustrated in U.S. Plant Pat. No. 12,681, are compared to ‘Poultc011’ in Chart 1.
